A wheel chock () has a profile that provides maximum restraining capacity when the wheel () is completely supported thereby, by mitigating undesirable failure modes while promoting the safest failure mode of operation, slipping on ground (). The profile includes a generally flat bottom surface () for being in contact with a ground surface (), a substantially broken top surface () for being in contact with the wheel (), the top surface () including a first contact point (P), a second contact point (P), and a contact surface () there between allowing at most two points of contact at a time between the contact surface () and the wheel (), with the second contact point (P) being one of the two points of contact. A more specific clothoid profile of the contact surface () is preferred to minimize the rate of variation of the contact force of the wheel () with the chock ().

Wheel chock device

In some embodiments, a redundant control system includes first and second control systems, having first and second clutches, and a shared clutch system. The shared clutch system may include a shared shaft configured to receive mechanical energy from a shared power source, a first shared clutch corresponding to the first clutch and configured to receive mechanical energy from the shared shaft, and a second shared clutch corresponding to the second clutch and configured to receive mechanical energy from the shared shaft. A first linkage provides mechanical communication between an output of the first clutch, an output of the first shared clutch, and a first output device in mechanical communication with the rotor system. A second linkage provides mechanical communication between an output of the second clutch, an output of the second shared clutch, and a second output device in mechanical communication with the rotor system.
